----------------------
* A problem creating CIDs on non-English workstations has been resolved
* Windows 95/98/Me CIDs are now created with data for all supported languages
All Sophos Anti-Virus versions have been updated with new virus information.
2. Important information for customers not using InterCheck
-----------------------------------------------------------
This version of Sophos Anti-Virus for Windows 95/98/Me does not correctly
perform on-startup scans. This issue does not affect customers using the
InterCheck on-access scanner.
Sophos recommends customers to use the InterCheck on-access scanner.
If you currently run Sophos Anti-Virus for Windows 95/98/Me as an on-demand
scanner only, and wish to run an on-startup scan, you should install the
alternative version available from http://www.sophos.com/downloads/products.
Enter (or apply for) your customer ID, click the link for 'Sophos Anti-Virus
for Windows 95/98/Me', and then download the 'NSV' version. Alternatively,
contact Sophos technical support.
3. General notes
----------------
a) Archive types
Archives are not scanned by default. To enable archive scanning, tick the
'Scan inside archives' box within Sophos Anti-Virus. Depending on the
number of archives present, scanning time may be increased.
Selecting archive scanning enables the scanning of ARJ, CMZ, GZIP, RAR,
TAR, ZIP, LHA, UUE, LZH archives, self-extracting archives of these types,
Zipmail files, and files compressed with MS Compress.
Self-extracting archives are only scanned as archives if archive handling
has been switched on for that archive type. Otherwise they will be scanned
only as executables.
If both archive scanning and Macintosh virus scanning are selected BinHex
and MacBinary files will also be scanned.
Unix ELF files are scanned either when their file extension is in the
executables list, or if 'All files' is selected.
The scanning of Microsoft Cabinet files is not enabled when archive file
handling is enabled. It can be enabled individually.
b) Extension list
The following file extensions are scanned for by default in immediate and
scheduled scans.
..., 386, 3GR, ADD, ASP, BAT, CHM, CMD, COM, CPL, DBX, DLL, DMD, DOC, DOT,
DRV, EML, EXE, FLT, FON, FOT, HLP, HT?, HTA, HTML, I13, IFS, INI, JS, JSE,
LNK, MOD, MPD, MPP, MPT, MSO, NWS, OCX, OV?, PDF, PDR, PIF, PL, POT, PPS,
PPT, PRC, RTF, SCR, SH, SHB, SHS, SRC, SWF, SYS, VB?, VXD, WBK, XL?,
4. Additional information
-------------------------
The following suggestions may require the use of the Registry Editor
(REGEDT32.EXE). Microsoft have issued the following warning with respect to
the Registry Editor:
"Using Registry Editor incorrectly can cause serious, system-wide problems
that may require you to reinstall Windows 95/98/Me to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk."
a) Setup
'SETUP /UPDATE' has priority over workstation installations,
i.e. 'SETUP /UPDATE' will not fail because a workstation is in the process
of establishing the need to upgrade or is in the process of upgrading.
Several command line qualifiers have been added to the setup program:
-a non-interactive install
-ni non-interactive setup
-in invisible setup program
-inl invisible loader
b) Messaging sub-system
Forcing the SMTP SMM to send its reports as MIME-encoded attachments is
possible. To do this add the following value to the registry:
Key: HLM\SOFTWARE\Sophos\Sweep95\SMMs\SMTP.smm
Value Name: Mime Encode
Type: REG_DWORD
Data: 0x00000001
c) Improved interaction with files held in off-line storage
By default, during immediate and scheduled scans, Sophos Anti-Virus will
not retrieve files marked as being held in off-line storage for scanning.
This default behaviour can be over-ridden by setting the following value in
the registry.
Key: HLM\Software\Sophos\ADVANCED\
Value Name: SCAN_FILES_IN_HSM
Type: REG_DWORD
Data: 0x00000001
d) Scanning during an update
Sophos Anti-Virus for Windows 95/98/Me scans memory, boot sectors and
system files during an update. If file copying is interrupted the process
will resume from the last complete file copied. It will not start again
from the beginning.
e) Virus information
When requesting information on viruses, users are directed towards the
Sophos web site for the most accurate up to date information.
5. Information from previous versions
-------------------------------------
October 2002 (3.62)
* InterCheck monitor icon colour change indicates InterCheck inactivity
The InterCheck Monitor arrow will now change from its usual red to grey to
indicate that InterCheck is disabled.
* Ability for Setup to remove unwanted shortcuts from the Start menu
Sophos items that no longer exist on the computer but appear in the Start
menu will now be removed.
* SAVI DLL now runs on both Windows NT/2000/XP and Windows 95/98/Me
SAV Iinterface (SAVI) developers will now be able to write products that can
be used on Windows 95/98/Me to complement those already available on Windows
NT/2000/XP.
* New information pages
There are new information pages available on this CD. You can view these
pages from any computer with an internet browser installed. They include
installing and updating advice, product information, documentation, and
contact information.
To view these pages, let the CD autorun or run 'LAUNCHCD.EXE' from the root
of the CD. If Internet Explorer 4.0 or above is installed on your computer,
the information pages are displayed in a special Sophos application that
enables you to install or update directly from the information pages.
With other browsers open 'index.htm' from the root of the CD.
If you have any difficulties viewing the CD's information pages, email
sophoscd@sophos.com.
* INTERCHK.CFG
In the absence of an existing INTERCHK.CFG file in the root of the Interchk
share, creating a new Windows 95 CID will create INTERCHK.CFG in the W95inst
folder.
6. Known problems
-----------------
None.
7. Compatibility issues
-----------------------
a) Bay Networks (Performance Technologies) Instant Internet
A conflict between the version of the WinSock client installed by the
Instant Internet application and the Sophos SMTP.SMM module can lead to the
Sophos Anti-Virus service not starting or stopping correctly.
As a work-around, add the following value to the registry.
Key: HKEY_LOCAL_MACHINE\Software\Sophos\Sweep95\SMMS\SMTP\
Value Name: No Startup Check
Type: REG_DWORD
Data: 0x1
This work-around will prevent the SMTP module checking for the appropriate
network transport protocols during startup.

2. General notes
----------------
a) Enabling archive scanning
It is possible to configure InterCheck to search for viruses inside
archives such as Zip or Tar. However, by default this facility has not been
enabled, and infected files stored in archives will not be reported until
they are extracted for use.
The ability to scan inside archive files is disabled by default because it
can take a long time to scan inside large archives and a user must wait
until the scan is complete before they can continue with their work.
However, in some circumstances it may still be desirable to enable scanning
inside archives. This section tells you how to do so.
The default action can be modified for the following archive formats:
Zip, Arj, Rar, Gzip, Tar and Cmz.
For example, to enable Zip file archive handling the following must be
added to the INTERCHK.CFG file:
[InterCheckGlobal]
AddProgramExtension=ZIP
[SweepVxDGlobal]
VirusEngineSetting:Zip=1
For the other archive formats, each needs to be added as above with a
separate AddProgramExtension entry for each different extension used and
one VirusEngineSetting entry for the archive type.
For example, to enable Tar and Zip file archive handling, where Zip files
may have the alternative extension WZP, the following must be added to the
INTERCHK.CFG file:
[InterCheckGlobal]
AddProgramExtension=ZIP
AddProgramExtension=WZP
AddProgramExtension=TAR
[SweepVxDGlobal]
VirusEngineSetting:Zip=1
VirusEngineSetting:Tar=1
b) Default program extension list
Any file whose extension matches an entry in the following list will be
considered by InterCheck to be a program and will be checked whenever it is
accessed:
ASP, BAT, CHM, CMD, COM, DBX, DLL, DOT, DRV, EML, EXE, HLP, HT?, INI, JS,
JSE, LNK, MPP, MPT, MSO, NWS, OCX, OV?, PDF, PIF, PL, PRC, RTF, SH, SHB,
SHS, SWF, SYS, VB?, VXD, WBK, XL?
3. Information from previous versions
-------------------------------------
Version 4.20
a) Removal of Networked mode support
InterCheck will only work with the Sweep95 VxD. It will ignore the
SweepVxDLoad configuration file option. The communications directory can
still be specified for messaging.
b) Upgrade SWEEP check level changed to SYSTEM
Previously a QUICK scan was performed for every update. Now with frequent
upgrades required as virus identities (IDEs) are made available on a daily
basis, the upgrade check level has been changed to SYSTEM to enable a
quicker startup.
c) Withdrawal of InterCheck for DOS/Windows 3.1x
On-access scanning is no longer supported on DOS/Windows 3.1x in any mode.
On-demand scanning of DOS/Windows 3.1x systems is still supported with DOS
SWEEP.
4. Additional information
-------------------------
a) Additional configuration options
AddProgramExtension=ext
This option adds ONE extension to the ProgramExtensions list, but leaves
the existing list alone. Note that if this option precedes a
ProgramExtensions= option, the single extension is discarded. To add "no
extension" to the list, use a dot by itself.
DriverIoChecking=YES|NO
If set to NO, this will suppress interception of certain types of file I/O
operations executed by other VxDs in the system. Use this option to avoid
problems (such as lock-ups) that can occur when InterCheck intercepts these
calls. One third-party product that definitely requires this switch set to
NO is ZIPMagic (1.0 and 98) from Mijenix. The default is YES.
DriveType=x:,type
This option allows the user to override the system's assignment of drive
types. It is primarily intended for use in the form DriveType=A:,FLOPPY
which allows InterCheck to start up without a delay on systems which have
no A: floppy drive. It can also be used where a PC boots up from a
removable C: drive in order to force InterCheck to treat the removable
drive as if it were a fixed hard disk.
x: may be any drive letter from A: to Z: (or a: to z:)
Type may be one of the following:
for floppy and other removable drives: FLOPPY,REMOVABLE
for non-removable drives: FIXED,HARD DISK,HARDDISK
for mapped network drive letters: NETWORK,REMOTE
for CD-ROM drives: CDROM,CD
for RAM disks: RAMDISK
when the drive doesn't exist: ABSENT,NONE
NOTE: This option only affects the actions taken by InterCheck during
startup.
5. Known problems
-----------------
a) Exclude= does not work correctly on InterCheck
InterCheck only allows the use of standard short "8.3" file names in the
"Exclude" configuration option. This means that it is not possible to
exclude files with long names (e.g. "longfilename.txt").
6. Compatibility issues
-----------------------
a) Windows 95 and USB support
On Windows 95 (OSR2) machines where the "USB (Universal Serial Bus)
supplement" has been installed, InterCheck may hang on startup displaying
the message "Preparing to SWEEP". The problem is caused by an obsolete
version of the USB supplement.
Customers encountering this problem are advised to remove the USB
supplement using the "Add/Remove programs" icon in the control panel. When
USB support is required, the latest version of the USB supplement should
then be installed.
b) Borland C++ and Novell IntraNetWare client
There is a problem when using Borland C++ 4.51 and the Novell IntraNetWare
client version 3.10 together with InterCheck for Windows 95/98. When
building large projects (20+ source files), files are left locked open and
cannot be deleted. This problem does not occur when using version 3.02 of
the Novell IntraNetWare client.
c) Windows 95 Program Manager
It is possible to configure Windows 95 to use a different shell instead of
the normal Explorer. Windows 95 includes a version of the Windows 3.1x
Program Manager which can be used as a shell.
Sophos recommends against using Program Manager as a shell on a machine
which runs InterCheck.
d) Hewlett Packard scanners and OCR software
If you experience problems such as system lock-ups or fatal exception
errors when using OCR software to acquire text directly from a Hewlett
Packard scanner while InterCheck is active, you should put the following
line in INTERCHK.CFG:
Exclude=HPSCAN
This prevents InterCheck from attempting to open a device name that is
associated with the scanner, and that causes fatal errors if it is opened
other than by the application.
e) Eudora
When Eudora is configured by a command line option to use a network drive
for its files, InterCheck causes it to be very slow. This is caused by
InterCheck's file type detection trying to identify the kind of file being
accessed.
The main "culprit" file is eudora.ini. You can improve performance by
adding:
Exclude=eudora.ini
to INTERCHK.CFG.
f) Mijenix Corporation's ZIPMagic
InterCheck 4.XX requires the use of the DriverIoChecking=NO configuration
file option when used with either ZIPMagic 1.0 or ZIPMagic 98.
g) AS/400 Client Access
The InterCheck client cannot be used with AS/400 Client Access because the
Sweep95 VxD is unable to open files stored on the AS/400.
h) Other memory resident Anti-Virus products
We do not recommend using InterCheck when other memory resident anti-virus
are active. Attempting to run multiple anti-virus products in this manner
will cause the system to run extremely slowly. In some cases the system may
also become unstable.
